3 Claims.

The invention relates to a trailer and more particularly to a wheeled vehicle used for hauling tractors and other heavy machines.I

The primary object of the invention is the provision of a trailer of this character wherein, through the use of cross pieces, the frame can be widened in conformity with the requirement of a load.

Another object of the invention is the provision of a trailer of this character which is simple in construction, thoroughly reliable and efcient in its purposes, light in weight yet strong, sturdy and durable, and also inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred embodiments of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a side elevation of a trailer constructed in accordance with the invention.

Figure 2 is a top plan View thereof.

'Figure 3 is a front elevation.

Figure 4 is a top plan view of a modified form.

Figure 5 is a side elevation thereof.

Figure 6 is a side elevation showing the truck hitched to a tractor.

Figure 7 is a side elevation of the trailer, this being the two double wheel trailer or the four wheel trailer.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the trailer in its construction comprises a pair of front stationary axles I0, these being arranged end to end, and a pair of rear axles II, likewise these being arranged end to end and having journaled thereon the rear wheels I2, there being four in number. 'I'he front axles I0 are fitted with turning knuckles I3, these supporting the front steering wheels I4, there being four in number.

Arranged over the axles I and II are pairs of sills I5, the sills of each pair being parallel with each other and in side by side contact one with the other. Each pair of sills I5. at their rear end portions, are supported upon bowed rear springs I6, each at its rear end connected to the said sills by a shackle II and at its front end by a pivot pin I3. The front portions of each pair of sills I are secured to the stationary front axle by coupling bolts I9, the springs I6 being joined toV the rear axles II through the medium of clips 20.

Arranged transversely between the sills are the cross beams or bars 2|, these being removably 5 seated in saddle pieces 22 xed to the innermost sills I5 of the pairs and these beams or bars 2I can be of any required length uniform with each other to give the proper width to the trailer in conformity with the load to be carried thereby.

Disposed between the pairs of sills I5 and the beams or bars 2l are crossed chains 23, their ends being made secure to the saddles 22, as at 24, and these chains prevent the spreading of the pairs of sills I5 with respect to each other and l5 avoid the accidental detachment of the beams or bars 2| from the saddles 22, the pairs of sills and the beams or bars constituting the body or truck portion of the trailer.

The turning knuckles I3 connected with each axle I0 operate in unison through the medium of a tie or connecting rod 25, while operating both of said rods 25 in unison is a hitch 26 for the coupling of the trailer to a power medium.

At the rear ends of the pairs of sills I5 are socket fittings 2'I for the detachable engagement therein of rearwardly inclined runway planks 28 so that a tractor, as illustrated at 29, or other heavy machinery, when upon the ground can be run onto the trailer for the transportation of said tractor or other heavy machine, as will be apparent.

The trailer in its construction really embraces a pair of four-wheel trucks, these being coupled together transversely with respect to each other and the front steering wheels oi both trucks being guided by a hitch.

In Figures 4, 5 and 6 of the drawings there is shown a modication of the invention, wherein the sills 30, which are the equivalent of the sills I5, have arranged therebetween the triangularshaped member 3|, its tapered end being foremost and joined with a cross piece 32 through the medium of a clevis 33 having a removable pin 34, so that the fore end of the triangular member can be detached from this bar 32, the latter being linked, at 35, to the sills 30. The triangularshaped member 3I and the cross piece at its rearmost end has connection with the sills by hinges 35 and these sills 30 have separable front end portions 3l detachably coupled, at 38, with the rear portions of said sills. The hinges 36 are of the double hinge type, so that the body can swing sidewise or move up and down. The triangular-shaped member 3|, at its underside, has

fixed thereto a cross rest bar 39, the same Ihaving its opposite ends freely received in yokes or saddles 46, onthe undersides of the sills 3U. This cross piece 39 is fixed with the triangular-shaped member 3l to lie slightly rearwardly of the points of separation of the fore portions 31 of the wheels 30 from the rear portions'thereof. It should be apparent that the fore portions 3l of the sills 3U which are supported. by the front wheels of Ythe trailer can be separated from the rear portions of said sills 39 by removing the clevis pin 34 and disconnecting the couplings 38, whereupon the front end of the triangular-shaped member 3l can be hitched. to a draft medium and thereby converting the trailer from the front wheeled type to the rear wheeled type, as the double pairs of rear wheels will be the sole traction for the said converted trailer. It will be apparent Vthat when the trailer has been converted, the sills 3%), that is, the rear portions separated from the fore portions, will rest directly upon the cross'bar 39 carried by the triangularshaped member 3 I, to be maintained in substantially the same plane with each other. This converted trailer functions for the hauling of trac-'- tors orother heavy'or light machinery. The triangular 3I and its cross pieces 32 and 39 may be readily removed from the sills by withdrawing the pintles for the hinges 35 and 3S and by sliding the cross piece 39 out of the saddles 4l] and thus render the sills independent of each other.

In VFigure 7 of the drawings there is shown the Y trailer which is ofthe two'double wheel type, or

what might be called a four-wheel trailer, having said axles, means located between the. sills for sustaining the same in their spaced side by side relation to each other, said means comprising spaced front/and rear cross members; Vand means on the confronting faces ofthe sills for removably pivoting said members to said sills for sepa.- ration therefrom to render the sills independent of each other.

2. A trailer of the character described comprising a pair of sills arranged side by side in spaced 10 parallel relation to each other and each having front and rear axles and wheels supported by Vsaid axles, means located between the sills for sus-4 -taining thesame in their spaced side by side Vrelation to each other, said means comprising oting the pointed end of the angle members to Y the front cross member, a cross bar xed to the angle members and, saddles carried by the sills in which the ends of theY cross bar are freely received.

3. A trailer of the character described comprising a pair of sills arranged side by side in spaced parallel relation to each other and each having front and rear axles and wheels supported by said axles, means located. between the sills for sustaining the same in their spaced side by side relation to each other, said means comprising a triangular member, inea-ns removably hinging the widened portion of said triangular member to the confronting sides of the sills, a cross member, means removably hinging the apex of the triangular member to the cross member, means removably hinging the ends' of the cross member to the confronting sidesof ther sills, a cross beam fixed to the triangular member, and saddles de the cross beam freely pass.
